Abstract
The electro-optic response in the C* phase of a side-chain polyacrylate and its monomer has been found to exhibit an anomalous dependence on temperature. The apparent tilt angle undergoes a sign reversal. The anomaly is attributed to a sign reversal of the spontaneous polarization, caused by molecular conformational changes in the monomer part.Keywords
